We just guessed the delta-v requirements. We'll send a rescue mission if they get stuck.

Is it bad if that's exactly what I do? To be honest, I don't even really know exactly what delta-v is and how to calculate it.

Not really. I do the same. In the worst case scenario, I just pack more fuel than I think is necessary.

/\v=Veln(M0/M1)...!

Delta-v is the capacity of your spacecraft to change its velocity. I imagine that you've noticed that maneuver nodes are always measured in units of velocity (namely, meters per second)? That's because it's a measure of how much you're expected to change your velocity. The equation above relates delta-v to your exhaust velocity (Ve) and your mass ratio (M0/M1). You might note that there is no variable for thrust there. That's not by mistake. Delta-v is independent of how long it takes to acquire it, which is the only thing your thrust can tell you. The logarithm there is the "diminishing returns" everyone talks about. You get less out of the same amount of remass the more you have.

Now, that's not to say that I build with a particular delta-v in mind. It's been a while since I had a delta-v display in the editor. But I do occasionally calculate the delta-v of a craft in situ. Note that both liquid fuel and oxidizer mass five kilograms per unit. Usually I do it with SSTOs, to see if I can go anywhere interesting.

"we at nasa only speak english and will never speak anithing else, and spend all possible effort to speak as much language as possible to help the futur beings, even if we can't promise we're gonna succeed or fail, we're just trying at best, it may just be another step in the universe history at our scale and until next"
